With the increasing global concern surrounding dementia and related cognitive problems in the elderly, being able to successfully prevent these issues is of great importance. JAMA Neurology conducted a study to research the effects of various forms of mental stimulation on cognitive delays in elderly participants. The study found several forms of mental stimulation that can reduce the risks of cognitive problems in the elderly. For instance, playing games and participating in regular social events was found to decrease the risk of cognitive delay by more than 20%. While participating in crafting activities can lower the risk by 28%, and learning to use a computer can reduce the risk as much as 30%. Maintaining a healthy lifestyle by choosing to eat healthy and exercise regularly has also been proven in many studies to reduce cognitive delay. Combining this with regular mental stimulation is a great way to help reduce the risks even further. According to Dr. Denise Park of the University of Texas, participating in new activities or tasks may be more effective than the repetition of familiar activities in preventing cognitive problems. Overall, it is important for older adults to participate in mentally stimulating activities and try to maintain a healthy lifestyle through proper diet and exercise. This may prove to be their best defense against cognitive decline.
